SymmetricState class

A class that represents a symmetric state in the Noise Protocol Framework.

Constructors

SymmetricState(CipherState cipherState, Uint8List ck, Uint8List h, NoiseHash hash)

Creates a new SymmetricState instance with the given cipher state, chaining key, hash value, and hash function.

Methods

decryptAndHash(Uint8List ciphertext) → Uint8List

Decrypts the input ciphertext with the cipher state and mixes the resulting plaintext into the hash value.

encryptAndHash(Uint8List plaintext) → Uint8List

Encrypts the input plaintext with the cipher state and mixes the resulting ciphertext into the hash value.

mixHash(Uint8List data) → void

Mixes the input data into the hash value.

mixKey(Uint8List inputKeyMaterial) → Future<void>

Mixes the input key material into the chaining key and updates the cipher state key.

mixKeyAndHash(Uint8List inputKeyMaterial) → Future<void>

Mixes the input key material into the chaining key, updates the hash value, and updates the cipher state key.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

split() → Future<List<CipherState>>

Splits the cipher state into two new cipher states using the current chaining key.

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.

Static Methods

initializeSymmetricState(Uint8List protocolName, NoiseHash hash, CipherState cipherState) → SymmetricState

Initializes a new SymmetricState instance with the given protocol name, hash function, and cipher state.
